The louse

The louse belongs to the order Phthiraptera. Clinging to hair, we can see the transparent moving lice before they have eaten. After having sucked the blood and juices of their victims they become more apparent, turning gray in color. A louse lays about eight nits (eggs) per day, or 250 during its life

The nit

The nit is the egg of the louse. When alive, it is bright, brown and situated at least 5 mm from the scalp. When the nit is more than 6 mm from the scalp, (which is caused by the growth of the hair) it is empty and whitish in color and attached to the host\’s hair with specialized saliva – a saliva/hair bond. Three weeks after incubation, the nymph releases itself from its shell and becomes a louse.

The spread

The louse crawls and stings. Spread occurs by direct contact of hair with hair or by the exchange of clothing. If your child has become infected with lice, it is recommended that you notify the school which he or she attends, and any close acquaintances in order to avoid further spreading. The invasion of lice is not due to a lack of hygiene and has no social preference. There is no reason to feel ashamed.

The life of the louse

The nit is the egg of the louse. The nit sticks by the cementum near the scalp when it is alive. It is 0.8 mm and its time of development is about seven days.

The nymph develops in three phases before becoming a louse. It becomes fertile during the last phase and it is from this stage that the Click'UP comb removes the parasites in the hair, preventing them from reproducing. The nymph is from 1 to 2 mm and its time of development is about 10 days.

The adult louse feeds on blood from the scalp and its saliva causes itching. A louse lays approximately eight nits per day and 250 nits during its life. It does not fly and does not jump, but it crawls very well and it easily propagates. The louse is from 1 to 3 mm and its life cycle is 30 days.
